> Key: MYFACES-3720
> URL: https://issues.apache.org/jira/browse/MYFACES-3720
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.1.10, 2.1.11
> Environment: 1. TomEE 1.6.0 snapshot (2013-04-29) which includes
> MyFaces 2.1.11
> 2. PrimeFaces 3.5 and PrimeFaces 4.0 snapshot
> Reporter: Howard W. Smith, Jr.
> Original Estimate: 28h
> Remaining Estimate: 28h
>
> Originally reported as OmniFaces issue # 167 (please take a look at this, as
> I attached some files there in OmniFaces issue tracker)
> https://code.google.com/p/omnifaces/issues/detail?id=167
> OmniFaces response was the following:
> Project Member #3 balusc
> This problem is indeed not related to o:enableRestorableView. The only
> occurrence in the stack trace is just the delegation to super (i.e. the
> process continues less or more as if the o:enableRestorableView was never
> involved):
> UIViewRoot restoredView = super.restoreView(context, viewId);
> Below is stack trace with TomEE 1.6.0 (2013-04-29), myFaces 2.1.11, and
> PrimeFaces 4.0 snapshot. Is this a MyFaces bug or user error?
